COOLING DEVICE FOR A PROTECTIVE RESPIRATORY APPARATUS

摘要

A cooling device (10), for a protective respiratory apparatus (100), has a housing (20), a breathing bag (30) arranged in the housing (20) with an inlet (32) for respiratory air (A) and an outlet (34) for cooled respiratory air (A) and a spring plate (40) with a spring device (42) to apply a spring force to the breathing bag (30). Between the housing (20) and at least one section of an outer side (36) of the breathing bag (30) an cooling air channel (50) is formed. The cooling air channel (50) is connected to the ambient air (U) outside the housing (20) in a fluid-communicating manner. A blower (52) is arranged for the generation of a flow of the ambient air (U) through the cooling air channel (50). Furthermore a protective respiratory apparatus (100) having such a cooling device is provided.
